## What is Trig Solver?

Trigonify brings the core tools for learning trigonometry into one focused, visual workspace. Solve a triangle, explore the unit circle, graph a function, review formulas, and practice the ideas behind each answer—without creating an account or seeing ads.

SOLVE WITH STEPS
• Solve right triangles with SOHCAHTOA and the Pythagorean theorem
• Find missing sides and angles with clear worked steps
• Use inverse sine, cosine, and tangent with domain guidance
• Switch between degrees, radians, gradians, and DMS
• Save solutions and return to them later

SEE HOW TRIG FITS TOGETHER
• Drag around an interactive unit circle
• View exact values, quadrants, and reference angles
• Graph sine, cosine, and tangent with live controls for amplitude, period, phase, and vertical shift
• Link a moving unit-circle point to its waveform in the phase-shift playground

STUDY AND PRACTICE
• Search a structured trigonometry formula reference
• Favorite the identities you use most
• Practice by topic, review mistakes, and track streaks and accuracy
• Use Exam Mode to hide solvers and answers while keeping reference tools available

BUILT FOR REAL STUDY
• No account required
• No advertising
• Light, dark, high-contrast, and reduced-motion options
• iPhone and iPad support
• Local app settings, favorites, history, and practice progress
